Hematopoeisis is adversely affected, most notably in itai-itai disease where severe anemia is observed, in association with marked suppression of erythropoietin production .

Apprenticeship is a combination of on-the-job training and related classroom instruction in which workers learn the practical and theoretical aspects of a highly skilled occupation. Apprenticeship programs are operated on a voluntary basis by employers, employer associations, or management and labor groups (unions).Federal and State Governments are also involved in that they promote the establishment of apprentice programs and provide technical assistance to program sponsors.he pay scale for apprentices is based on wages of a âJourneymenâ (i.e., workers who have completed the program), and may start at about 35% to 50% of the Journeyman rate. Apprentices receive pay increases as they advance through the program. Such increases may occur every six months or every year.
